Just to clarify, the three Confederate cavalry brigades under Jackson's command were led by Armstrong, Ross and Harrison. The last two were involved in "Red" Jackson's pursuit and capture of McCook's command, the final battle taking place on July 30th at Brown's Mill. This was probably the most decisive victory in Joe Wheeler's military career.
Here's Sherman's description of his defenses --
General Blair's came into line on his right early in the morning of the 28th, his right reaching an old meeting-house called Ezra Church near some large open fields by the poor-house on a road known as the Bell's Ferry road or Lick Skillet road. Here the Fifteenth Corps (General Logan's) joined on and refused along a ridge well wooded, which partially commanded a view over the same fields. About 10 a.m. all the army was in position and the men were busy in throwing up the accustomed pile of rails and logs, which after a while assumed the form of a parapet. The skill and rapidity with which our men construct these is wonderful and is something new in the art of war.
If I recall, on the morning of July 28th Armstrong and Ross were attempting to delay the advance of Blair's Corps.
To my knowledge Stephen D. Lee never expressed remorse over Confederate losses suffered as a result of one of his useless and foolish attacks. In his report of the Battle of Lickskillet Road, Lee wrote --
The enemy had two corps engaged in this affair; still I am convinced that if all the troops had displayed equal spirit we would have been successful, as the enemy's works were slight, and besides they had scarcely gotten into position when we made the attack.
